Abstract: This report provides a description of an OpenFOAM script for constructing fully hexahedral meshes for a variety of different pipeline geometries. This script allows to change several length scales as well as some useful geometrical parameters concerning the refinement of the mesh, for example close to the walls to resolve boundary layers.
The aim of the mesh generator tool is to extent the blockMesh utility in such a way that it allows to create arbitrary geometries consisting of bends, blind-Ts, Venturi parts, and straight pipes. For the different parts, the following parameters can be adapted to the considered geometry:
• Bend: diameter of the pipe, radius of curvature, orientation in space
• Blind-T: diameter of inflow pipe, diameter of outflow pipe, length of blind end, orientation in space
• Venturi part: inlet diameter, throat diameter, outlet diameter, convection angle, divergence angle, orientation in space
• Straight pipe: diameter of pipe, orientation in space.
Furthermore, one can prescribe the number of nodes used in flow direction, in radial direction as well as within the boundary layer.
